Low-cost high-strength Fe-containing near-Beta titanium alloy and preparation method thereof

The invention discloses a low-cost high-strength Fe-containing near-Beta titanium alloy. The titanium alloy is characterized by comprising the following alloy elements in percentage by weight: 2.5%-5.5% of Al; 0.5%-2.2% of Fe; 4.7%-5.7% of Mo; 3.5%-4.5% of Cr; 1.5%-3.5% of Zr; and Ti and inevitable impurities in balancing amount. According to the titanium alloy, cheap elements such as Fe, Al and Zr are employed to replace expensive elements such as V on the basis that the mechanical properties of the titanium alloy are guaranteed, so that the cost of the titanium alloy is greatly reduced.
